Amazing that no one was hurt. I'll never walk under a train trestle again the same way.
I've driven over that bridge and I recall that the design is very unusual. The central part of the bridge is built for vehicles and the RR tracks are built on the side of the bridge, almost like a ledge. You can sort of tell in the photos.
My recollection is off. I do remember thinking how unusual and scary the bridge was. I did not enjoy driving over it.
It was really built for trains, and the car lanes were an afterthought. First fixed crossing of the Mississippi in the New Orleans area.
Winds in a storm back in the old country were so strong that a couple of train cars carrying shipping containers blew off the Huey P. Long Bridge, maybe a half mile from the River. That they were empty, that they were not over the river, and that nobody was injured makes this a bit less sensational; but even so, Nature, she's a wild one. Video caught by chance by a reporter for one of the local networks who flipped on his dash cam just in time.
